Definitions

  • Hollow filaments having permeable walls for installation in fluid separatory modules must be arranged in a bundle and be sealed in a tube sheet at one or both ends.
  • a bundle of straight parallel filaments causes inefficiencies in the separatory process, and conversely a bundle comprising criss-crossed filaments with an even distribution of connected tortuous voids between the filaments can promote the separating efficiency.
  • a properly assembled multifilament bundle must meet a number of requirements. Among these is a geometric arrangement which provides a fairly high packing density of the filaments and which at the same time minimizes channeling of the feed fluid as it passes among the filaments. Therefore, some method of keeping the filaments from packing densely in some ares and loosely in others is desirable. In other words, the packing density of the filaments in the bundle should be both very uniform, and in the order of about 25% to 60%, if some of the main advantages of the use of hollow filaments separatory modules are to be achieved. In view of these considerations the use of various filament assembly techniques is frequently unattractive.
  • the o6ject of the present invention is to form coreless filament bundles by the winding and cutting technique just described, but in such a way that the filaments in the segments which form the bundles, follow improved helical paths crossing over each other.
  • such a method comprises providing a drum with a plurality of radially outwardly projecting and axially extending vanes spaced apart around the drum so that the tangential distances between the radially outer edges of the vanes is equal to or greater than the length of the filament bundles to be made, winding a filament around the vanes to provide a winding formed of left-hand and right-hand helices with turns of the left-hand and right-hand helices crossing over each other at crossing points, sliding the winding along the drum and thereby trellising the crossing points or rolling the winding up axially of the drum so that the axial length of the winding on the drum is reduced and the turns of the winding form an annular rope around the drum and then tying segments of the rope between adjacent vanes and cutting the segments from the drum, each segment forming a bundle.
  • the invention also consists in a hollow filament bundle for a separatory module made by the method in accordance with the invention.
  • the main part of a winding machine used in carrying out the method of the invention is a large rotatable drum.
  • a filament bundle in the process of being wound is indicated by the numeral 20 while the drum is indicated by the numeral 22.
  • the drum has axially extending vanes 24.
  • the size of the drum is such that the tangential distance between the tips of adjacent vanes 24 is equal to or slightly greater than the desired length of the filament bundles to be made on the drum.
  • the drum is rotated around its own axis and hollow filaments from a number of supply packages are wound helically around the vanes 24.
  • a traversing mechanism 26 is provided so that alternating layers of the winding traverse in opposite directions, and create a winding pattern with a multiplicity of filament crossovers.
  • the filaments are wound on to the rotating drum as shown in Figures 2A and 2B.
  • the winding pattern must also provide a level wind traverse, so that a pattern of left and right-hand helices, with multiple crossovers is created as shown in Figure 2B.
  • the roped or' rolled-up bundle is tied or bound together by ties 30 between the vanes, and then individual segments of annular rope, each segment extending between adjacent vanes are cut off the winding drum, and are ready for potting the end seals, or other necessary processing steps to form the module.
  • the cross-section of each segment which forms a bundle can be manipulated to provide a nearly circular or rectangular shape as may be necessary according to the end use of the module.
  • the bundle When the bundle has been built up to the desired final cross-section and has had its ends potted, it can be inserted in a cylindrical chamber and be sealed in the chamber to provide a. completed module.
